24 Claims.

The present invention has to do with improvements in a skate and more particularly to a foldable key continuously carried thereby.

It is an object of the invention to provide a 5 skate having complementary clamping elements controlled by a rotatable member carrying foldable key means normally out of axial alinement with the latter and adapted to be conveniently and readily extended in axial alinement therewith 10 for adjustably actuating the clamping members simultaneously.

It is another objectof the invention to provide a skate having companion slidable sections clamped together by a rotatable adjustably con- 15 trolled member continuously carrying a foldable or collapsible key which may be quickly and operatively extended to control the clamping relation of the companion sections.

Other objects, advantages, and features of the invention are in part obvious and in part pointed out hereinafter.

For a clearer understanding of the invention attention is directed to the preferred embodiment shown in the accompanying drawings in which:

Fig. l is a plan view or" the skate according to the invention, illustrating the front key for the complementary clamping elements extended, and the rear key for adjustably holding the slidabl iront and rear sections, folded.

Fig. 2 is a iront View of Fig. l, illustrating in dash and dot lines the front key for the complementary clamping elements partially collapsed.

Fig. 3 is a View similar to Fig. 2 showing the iront key fully collapsed.

Fig. 4 is a section taken on the line li-ll of Fig. 2.

Fig. 5 is a fragmentary side View of a iront or toe portion of the skate showing two selective settable positions of the key after having been 1U fOlded.

Fig. 6 is a view' similar to Fig. l showing both oi the ioldable keys extended.

Fig. is a section on the line l-'l of Fig. 6 illustrating the complementary slidable plate sec- .15 tions unclamped.

Fig. 8 is a view similar to Fig. 7 showing the Iii) complementary sections clamped and the control carrying a depending support as 53 each including a fixed transverse shaft It on which wheels I5 are rotatably supported in a manner well understood.

Associated with the iront or toe section ll is a pair of complementary clamping elements or jaws it and Vl having inwardly disposed depending appropriately perforated ears E8 threadably and adjustably connected to a common rotatable member or threaded shank i9 comprising an intermediate attenuated portion 22 rotatably sustained in a perforated centrally arranged lug 23 depending from the front toe section, Il.

Spaced guide pins 2li carried by section ii cooperate with slots 25 in an intermediate horizontal respective portion` 26 of the clamping jaws to permit the latter to be rectilinearly moved to and from the sides oi the section i I when shank or threaded bolt i9 is rotated relative to the rectilinearly displaceable depending ears i8 of the pair of clamping jaws l5 and Il.

As shown, bolt 2S is externally threaded and includes a group oi threads 2l extending in a direction to the left and a group of threads 28 extending in a direction to the right, the right and left threads of the bolt cooperate with companion threads in the spaced depending ears l 8 to move the clamping jaws bodily towards each other when the bolt is rotated in one direction and to move the complementary jaws bodily away from each other when the bolt is rotated in an opposite direction.

Appropriately attached to adjustable bolt i9 is a collapsible or foldable key broadly denoted 29 which comprises a cylindrical shank 3i) having alined wings or manipulative portions 3l adapted to be grasped by the operator for rotating shank or rod 3Q.

According to the invention, means is provided for bodily rotating or adjusting bolt I9 in the event key 29 is rotated. To this end, the adjacent terminals 32 and 33 of the key and bolt are interconnected by a common link 3ft having its opposite terminals pivotally sustained on xed pins 35, and 36 xedly anchored across the key and bolt respectively. More specifically adjacent terminals 32 and S3 each include a slot 3l dening spaced ears or lugs 38 straddling a companion end of swingable link 34 and forming a bifurcation in association with a shoulder 39 constituted by the innermost wall of a respective slot 31.

Each of the faces 4D of link 3A is irregularly shaped to provide spaced but curved cam faces 4l and 42 which are interconnected by a central inwardly disposed concayity or arcuate face 43 defining a locking pocket or recess for an associated spring actuated cylindrical tumbler 4d yieldingly and slidably sustained in axially arranged bores 55 in the adjacent terminals 32 and 33 of the key and bolt.

Disposed within each bore 45 of the key and bolt is a helicoidal spring 45 normally urging an associated tumbler against a companion end as 45 of swingable link 34 pivotally` connected to adjacent terminals of the key and bolt.

As illustrated in Fig. 2, key 29 is in axial alinement with threaded bolt i9. The key is held in alinement by reason of the locking cylindrical tumblers urged by companion springs 45 within or interiocking with a respective concavity or recess 43 at an associated end of the swingable link 34.

In the locked and alined position of the key and bolt, the latter may be bodily rotated in unison with the key, if the key be rotated. Consequently, the internally threaded spaced ears may be adjustably positioned relative to the bolt and hence complementary clamping elements i6 and Il may be adjustably set to clamp the toe portion of a sole of a shoe interposed between the clamping elements.

Having completed adjustment of the clamping elements in respect to bolt I9, the key may be quickly folded or collapsed to be disposed underneath toe section H. In this connection, key 29 is swung inwardly, namely, it is pivoted on fulcrum pin 35 and moved downwardly relative to the link and bolt which are held in alinement (see dot and dash lines Fig. 2). Following this operation, the key and link form a crank or elbow which may be bodily moved inwardly relative to the plate section Il and swung on iixed fulcrum pivot pin 35. Accordingly key 29 takes the position shown in Fig. 3, namely, substantially parallel to the bolt I9. As shown in full lines in Fig. 5, the key 29 and its wing portion 3! are disposed at the rear 0i the complementary clamping elements l5 and H while the dash and dot lines show the key tolded so as to be selectively sustained in front of the complementary clamping elements.

In Figs. 3 and 5, the key is folded and out of the way. If it be desired to disconnect the complementary elements I6 and l? from a shoe, the key is extended to be in alinement with the threaded bolt i9. For this purpose shank 35 may be pivotally swung downwardly pivoting on pin 35 relative to link 34 to be in line therewith. Subsequently both the key and link are bodily swung on pivot pin 35 to dispose both the key and link in axial alinement with the bolt. The key 29 now extends laterally of the toe section Il and may be rotated to adjust the bolt and hence elements i6 and il, the link transmitting the rotary motion of the key to the bolt as is well understood.

In the alined position of the bolt and key, a slidable locking tumbler 40 is in part disposed in a respective cooperating recess by a companion spring 45, thus preventing displacement of the key relative to the link and/or bolt or the link in respect to the key and/ or bolt. In other words the spring actuated tumblers hold the link in alinement with the bolt and key when the latter is extended laterally preparatory to adjusting the bolt.

When the key is swung relative to the link, a cam face as 4l acts on the companion tumbler displacing the latter against its spring 46 and consequently permitting the key to assume a position perpendicular to the link in which position it is held by its companion tumbier which is automatically urged against a side of the link by its associated spring. It follows therefore that tumbler 45 and spring 46 of the key holds one end of the link against shoulder 39 of the key.

With the key now at right angles to the link to form a crank therewith and it is desired to dispose the key parallel to bolt, the crank is swung bodily on pivot 35. During this movement, first the tumbler carried by the bolt is depressed by a cam face 42 to disconnect the tumbler irom an associated end of the link thus permitting the latter to swing relative to the bolt and subsequently the link takes a position perpendicular tothe bolt with the key parallel to the latter. In such a relation, the outward thrust of spring 46 of the bolt urges its associated tumbler against a side of the link to hold the latter in` its set position against shoulder 39 of the bolt. That is to say, if the bolt be extended, it is set and locked and will stay in such position until manually disturbed and if the bolt be in collapsed position, it will automatically be retained or held folded.

The key is also held in a selected ioldable position after the complementary clamping elements l5 and il are clamped to a sole portion of a shoe as a result of an outwardly directed thrust imparted to the bolt by the clamping elements when the latter are gripping the sides of a shoe.

As previously stated, toe plate section l l is slidable relative to heel or rear companion plate section I2. More particularly, section ll comprises an attenuated rear portion having a longitudinally disposed elongated slot 5l and depending side flanges 52 and 53. The rear portion of heel section l2 comprises a split yoke or channel 54 having depending ears and 56 straddling depending flanges 52 and 53 of section Il.

Section l2 is slidably guided relative to section Il by a suitable pin 5I carried by section i2 and rectilinearly guided in slot 5|. The depending ears 55 and 56 of yoke 54 rotatably Support the transversely disposed adjustable bolt 58 having suitable threads 59, which coact with the threads of the perforated ear 55.

One end oi bolt 58 includes a reduced portion G loosely rotatably supported in a perforation 5l in ear 55. The reduced portion 55 is provided with a head 62 of a diameter larger than open ing or perforation 6I.

In Fig. '7, depending ears 55 and 56 are slightly spaced from depending flanges 52 and 53. Consequently section II may be slidably moved either towards or away from section l2. In this relation head 52 of the bolt is slightly spaced from its cooperating ear 55 of yoke 54. If it is now assumed that the rear foldable key 29 in Fig. '7 is identical in construction and operation to the front key more particularly disclosed in connection with Figs. 1 5 inclusive and is extended and it is desired to clamp the complementary slidable metal section or members Il and l2 together to prevent displacement of the latter, the rear key is rotated and hence bolt 5S is rotated, causing head A52 to abut ear 55. Further rotation of the rear key in the same direction causes the depend ing resilient ears 55 and 55 of channel 54 to move towards each other and thus closely and frictionally embrace depending anges 52 and 53 of the front section Il (see Fig. 8). In other words,

the channel 54 of the rear section maybe appropriately and adjustably clamped against the rear portion of front section il. With the complementary sections clamped together as shown in Fig. 8 the rear key 29 may be folded inwardly and out of the way, namely, swung as to be disposed at one side of its bolt and substantially parallel thereto.

To provide a deadlock means to prevent longitudinal slippage of one section relative to the other after having been clamped together as previously explained, ear 56 of yoke 54 includes an inwardly disposed detent B3 cooperating with adjacent sides as 6d and 65 oi notches formed by the spaced teeth EE of iiange 53 of section Il. When the ears of the yoke are brought towards each other to clamp the sections together, detent 63 falls into a notch between a pair of teeth of flanges 53 forming a supplemental or dead lock to prevent longitudinal displacement of the 'companion plate sections relative to each other.

The heel portion l2 is provided with a longitudinal striation 61 bisecting the channel into spaced resilient components 68 and 69 which are brought towards each other when the rear key is rotated to clamp the sections together and which are moved away from each other when the sections are unclamped.

While reference in the specification and claims is made to the term skate, and the drawings merely illustrate a roller skate, it is recognized that the invention need not be limited to a roller skate and obviously the foldable key feature as disclosed may be employed in connection with any type of skate other than the form herein set forth, for example, if desired the foldable key of the present invention may be applied to ice skates or the like and consequently strict interpretaton of the term, skate, as herein utilized is therefore not contemplated.
